Module tornado.api

Package uk.ac.manchester.tornado.api.types.matrix

Class Matrix4x4Float

java.lang.Object

uk.ac.manchester.tornado.api.types.matrix.Matrix4x4Float

All Implemented Interfaces:

Serializable, PrimitiveStorage<FloatBuffer>, TornadoMatrixInterface<FloatBuffer>

public final class Matrix4x4Float
extends Object
implements TornadoMatrixInterface<FloatBuffer>

Matrix4x4Float relies on preview features of the Java platform:

• Matrix4x4Float refers to one or more preview APIs: MemorySegment.

Programs can only use Matrix4x4Float when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
